Overview of convection and radiation in high temperature gas flows

Abstract

A literature overview is presented of radiative and convective heat transfer in high temperature gas flows. The primary thrust is on fundamentals, but current technological applications of the complex phenomena involving, not only spectrally selective radiative transfer in common gases, but also turbulent chemically reacting flows, are discussed. The infrared radiation gas property models and methods for solving the radiative transfer equation are highlighted first. Then, convective and radiative heat transfer in channels and chemically reacting high temperature flows are reviewed. The nonlinear effects of turbulent fluctuations in radiative transfer, and the influence of radiation on thermal turbulence spectra are also considered. Critical issues which need to be addressed for a more complete understanding of the processes are raised, and topics requiring research attention are identified.
